CHAMBER SPRING ATTACHMENT.

Application filed June 24, 1920.

To all whom it may concern:

Be it known that l, LEVI R. H. DICK, a citizen of the United States,.residing at- Chicago, in the county of Cook and State of lllinois, haveinvented new and useful lmprovements in Chamber Spring Attacln ments, ofwhich the following is a specification.

This invention relates to means for holdin a vessel to the bottom of aseat and the principal object of the invention is to provide spring loopdetachably engaging the vessel with means for supporting the loop sothat it may expand and contract while being firmly supported from theseat.

Another object of the invention is to so form the ends of the loopmember that the vessel may be easily inserted between said ends orwithdrawn therefrom.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is a side view showing the invention in use.

Figure 2 is a bottom view.

Figure 3 is a detail view of one of the brackets.

In these views 1 indicates the seat and 2 indicates the vessel. Thisvessel is adapted to be supported from the seat and it is provided witha rim 3 which is engaged by the ring member l which may be formed from ametal rod. This member is supported from the bottom of the seat by thebrackets 5 and 6. The bracket 5 is of sub- Specification of LettersPatent.

stantially Z-shape with one part suitably secured to the bottom of theseat and its free end formed with the eye 6 to receive the ring member.This bracket engages that part of the ring member which is opposite theopening in said member. I use a pair of the brackets 6 and each of thesebrackets is made somewhat similar to the bracket '5 but its free end isextended to the central offset part so as to form an elongated eye 7 toreceive the ring member. In. this way the part of the ring memberengaged by said elongated eye have movement in said eye, thus permittingthe jaws 8 formed at the ends of the ring member to be moved apart topermit entrance of the vessel. The

brackets 6 are opposite each other and are spaced about from the bracket5. The jaws 8 are formed by curving the ends of the ring memberoutwardly as shown.

It will thus be seen that the vessel may be easily passed between thejaws so that its rim will be engaged by the ring member and p Thecombination with a seat, of a ring shaped clamping member having itsends spaced apart, a Z-shaped bracket having an eye for engaging thering member and another bracket having an elongated eye for movablyengaging the ring.

In testimony whereof I afiix my LEVI R. H. DICK.
